In a p-n junction, what is formed at the junction region?

Step 1: Understand what a p-n junction is. It is a boundary between two types of semiconductor materials: p-type (positive) and n-type (negative).
Step 2: Know that p-type has more holes (positive charge carriers) and n-type has more electrons (negative charge carriers).
Step 3: When the p-type and n-type materials are joined, electrons from the n-type region move towards the p-type region.
Step 4: Similarly, holes from the p-type region move towards the n-type region.
Step 5: This movement of charge carriers (electrons and holes) creates a region near the junction where there are no free charge carriers, called the depletion region.
Step 6: As electrons and holes move, they leave behind charged ions, creating an electric field in the depletion region.
Step 7: This electric field affects how the junction behaves, allowing current to flow in one direction but not the other.
